FIELD: machine building.
SUBSTANCE: electric energy transferred to a spark plug (S) and the temperature of a combustion chamber are determined. The S temperature is forecast and the forecast S temperature is used to control the supply of electric energy to the S. The forecast S temperature is calculated basing on the numerical solution of the differential equation (DE) for the S temperature. The DE for the S temperature is non-linear one by the S temperature. The DE for the S temperature is deduced from the power balance equation comprising at least four members Pg, Pi, Pe, Pc, where Pg simulates the electric energy supplied to the S, Pi simulates the energy accumulated in the S per time unit, Pe simulates radiant energy per time unit, and Pc simulates heat energy per time unit, the heat energy is transferred by convection or thermal conductivity.
EFFECT: higher accuracy of temperature control.
